R_g represents the radius of gyration determined by Guinier analysis

d_max represents the maximum distance constraint in the pairwise distance distribution or P(r) generation.

r_avg is the average radius from the P(r) distribution

P_x is the Porod exponent; larger values represent more compact particles.

Above parameters were determined with Scatter: (biosis.net)
